ABSTRACT

The invention relates to an umbrella frame having secure main branch rib, which mainly relates to be applied on the umbrella frame having odd ribs. The frame has a secure main branch rib with upward U-shape opening and a supplementary rib having inner hook to connect with the main branch rib. Hence, when the umbrella is closed, it will be secure and effective for users.

FIELD OF THE INVENTION

The present invention relates to an improvement of an umbrella frame,particularly to a frame having odd ribs, which includes a secure mainbranch rib for safe use.

BACKGROUND OF THE INVENTION

As shown in FIG. 1, it shows a conventional three-folded umbrellaincluding a first rib (1), a second rib (2), and a tail rib (3). A mainbranch rib (11) has its outer end connect with middle portion of thefirst rib (1). A first supplementary rib (12) is provided between theinner end of the second rib (2) and outer portion of the main branch rib(11). Due to the structure of the first supplementary rib (12), the mainbranch rib (11) must be provided with its U-shape open end downward forreceiving the supplementary rib (12) when the frame is closed. It is tobe found that the downward opening of the main branch rib (11) will hurtpeople's hand or fingers when he is pushing a runner upward to open theumbrella.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer to FIG. 2, it shows an embodiment of the present inventionhaving three ribs, which includes a first rib (1), a second rib, (2),and a tail rib (3). The improvement of the present invention is toprovide a main branch rib (13) having its U-shape opening upward. Themain branch rib (13) has its outer end connect with a middle portion ofthe first rib (1). A first supplementary rib (14) is a rod and has itsinner end to be a hook (141) to hook the outer portion of the mainbranch rib (13). Accordingly, when the umbrella is closed, the firstsupplementary rib (14) can be totally received in the first rib (1)without any disturbance.

Since the U-shape opening of the main branch rib (13) is upward, it willnot hurt any user's hand or fingers even he touches the rib (13) whenopening the umbrella. It is to be understood that the secure main branchrib can overcome the drawback of the prior arts.

Under the spirit as above mention, the present invention can be utilizedin an umbrella frame, which includes odd ribs. Such as shown in FIG. 3,it discloses an embodiment having five ribs.
